Definition

Solar hot water systems heat water by solar energy. Such systems consist of solar collectors, a fluid system that absorbs the sun energy, and a reservoir for heat storage for later use. The system may be used to heat water for home, swimming pools, or for space heating and cooling and more.

K-12 Experiments, DIY, Labs, Science Fair Projects

Build a solar collector and demonstrate how solar hot water can be made. [View Experiment]

Many designs for solar water heaters circulate water through a series of coiled or looped tubes in a collector box with a transparent cover facing the sun. In this activity, you will find out if such a design really works. [View Experiment]
